Groundhog Repellents
There are numerous products on the market that claim to get rid of groundhogs. The woodchuck's burrow system is approximately four feet deep, has several entry points and usually extends twenty five feet horizontally. When threatened, the groundhog will retreat to this underground fortress. Groundhog spray repellents, coyote urine, mothballs, ammonia and ultrasonic sound emitting devices, at best may make the groundhogs uncomfortable, but won't convince them to leave their underground bunker. When it comes to groundhog removal and control, repellents are ineffective.
